A Quick Tour of GNOME Shell

"Note the Activity menu and the specially-capulated notification
area. Good stuff. I al so like the stylized panel, but I
don’t like it at the top. When openSUSE adopts GNOME 3,
I’d like to see it moved to the bottom.

"Clicking on the Activity menu opens this menu. The desktop
shrinks into a side (and you can create or remove as many as you
wish, which is seriously awesome), and opens the most recent
Applications and documents (I think). If you wish to open an
application, double-click or drag the icon onto the desktop you
wish it to open to."
